Despite that No. 63 ranked schedule, advanced rankings (i.e. Sagarin had them at No. 7) looked at Wisconsin as a very, very good team. Winning 13 games isn't easy.
Wisconsin is a good team, and I believe on the rise. Still, very plausible that Nebraska can get a victory.
P.S. Your Sagarin example defeats your intended argument. Sagarin is an ELO method, a popular competitive ranking system but one that still relies on win-loss information with a SOS filter (essentially what ELO is). Because of this, his final rankings has Wisconsin behind all P5 one and two loss teams and one spot ahead of a four loss Auburn.
There's also no reason Indiana can't win the West.
I can think of one.
